I work at not acting differently based on what I am wearing. I have never been a "macho" male and for a long time, I was wondering when I was going to "grow up" and become a "man". Hmm, didn't work out... It never happened, or it did and I can't tell the difference!
When I first started dressing, I did act differently, more passive. However, my SO pointed that out to me, so I go for the balance instead. My notion is to stand tall and proud, no matter what I am wearing and be the best reflection of "me" that I can, period. I don't put on "airs", I don't pretend to be something I am not. Heck, I already am transgendered, that ought to be close enough no matter what I am wearing!
